This study investigated the efficacy and safety of budesonide/formoterol (B/F) and tiotropium combination in the management of chronic obstructive pulmonary disease (COPD) in Chinese patients.Between January 2015 and November 2017, 113 eligible Chinese patients with COPD were included and divided into an intervention group and a control group. Sixty-three patients in the intervention group underwent B/F combined tiotropium, while 50 patients in the control group received tiotropium alone. The primary outcome was severity of dyspnea on exertion (DOE), measured by the 6-minute walk test (6MWT) scale. The secondary outcomes included lung function, measured by the forced expiratory volume in 1 second (FEV1), quality of life, measured by the St. George's Respiratory Questionnaire (SGRQ), and adverse events. All outcomes were measured at the end of 12-week treatment.B/F and tiotropium combination showed greater efficacy in DOE (P < .01), lung function (P < .01), and quality of life (P < .01), compared with tiotropium alone at the end of 12-week treatment. In addition, adverse events in both groups were similar and tolerable.The findings suggest that B/F and tiotropium combination can be used as an effective treatment in Chinese patients with COPD.

Background:Previous clinical studies have reported that urapidil can effectively treat patients with senile hypertension (SH) and acute heart failure (AHF). However, no studies have systematically assessed the efficacy and safety of urapidil for patients with SH and AHF. Thus, this study will investigate the efficacy and safety of urapidil for SH and AHF.Methods:In this study, we will search the following electronic databases from inception to the June 30, 2019: MEDLINE, EMBASE, Cochrane Library, Google scholar, Springer, WANGFANG, and China Knowledge Resource Integrated Database. We will search all these electronic databases without language limitations. We will also search grey records to avoid missing potential literature. In this study, only randomized controlled trials on assessing efficacy and safety of urapidil for SH and AHF will be considered. We will use RevMan 5.3 software and STATA 15.0 software to carry out statistical analysis.Results:This study will evaluate the efficacy and safety of urapidil for SH and AHF by assessing all-cause mortality, change in body weight, urine output, change in serum sodium; and incidence of all adverse events.Conclusion:This study will provide latest evidence of the efficacy and safety of urapidil for patients with SH and AHF.Dissemination and ethics:This study will only analyze published data; therefore, no ethical approval is needed. The findings of this study will be published at peer-reviewed journals.Systematic review registration:PROSPERO CRD42019139344.

Background:This study will systematically investigate the efficacy and safety of methylprednisolone for treatment of persistent vertigo (PV).Methods:All following electronic databases will be searched from inception to the June 30, 2019 without language restrictions: MEDILINE, EMBASE, Cochrane Library, Web of Science, and Chinese Biomedical Literature Database. All randomized controlled trials focusing on assessing the efficacy and safety of methylprednisolone for patients with PV will be fully considered for inclusion. Cochrane risk of bias tool will be used for assessing methodological quality, and RevMan 5.3 software (Cochrane Community, London, UK) will be utilized for statistical analysis.Results:This study will assess the efficacy and safety of methylprednisolone for PV via assessing primary outcome of vertigo, and secondary outcomes of somatization, depression, anxiety, health-related quality of life, and adverse events.Conclusion:This study will provide a high-quality evidence to judge whether methylprednisolone is an effective and safety therapy for patients with PV.Dissemination and ethics:No individual data will be utilized in this study, thus, it does not need ethical approval. The results of this study will be published at peer-reviewed journals.Systematic review registration:PROSPERO CRD42019138890.
